Cooking container comprising a temperature sensor provided with a fixing member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking vessels with integrated temperature sensors suffer from inaccurate temperature measurement due to the sensor's unstable contact with the bottom, leading to variable response times and reduced heat transmission efficiency, especially when used with induction heating devices.
Innovation Solution
A cooking vessel design featuring a temperature sensor secured to a fixing element within the cap, which is immobilized against the bottom using a crimped fixing plate, ensuring stable contact and accurate temperature measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the temperature sensor is arranged between the bottom and the perforated plate without a fixing element, then the sensor can move freely during heating and cooling cycles, but the temperature measurement becomes inaccurate and response time becomes variable
Solution Approach 1:
A fixing element is introduced as an intermediary component between the temperature sensor and the bottom surface. This fixing element maintains stable thermal contact between the sensor and the bottom while allowing the sensor to remain positioned between the bottom and the perforated plate, thus resolving the contradiction between movement freedom and measurement accuracy.
2Loss of energy
If the perforated plate is fixed to the bottom to ensure induction heating compatibility, then heat transmission improves, but the sensor may move against the plate causing hot spots and inaccurate measurements
Solution Approach 1:
The system is segmented into distinct functional components: the bottom surface, the fixing element, the temperature sensor, and the perforated plate. The fixing element is specifically designed to secure the sensor independently while the perforated plate remains fixed for induction heating compatibility. This segmentation allows each component to fulfill its specific function without interfering with others, resolving the contradiction between heat transmission efficiency and measurement reliability.
3Measurement precision
If the sensor is directly fixed to the bottom, then stable temperature measurement is achieved, but the sensor is vulnerable to damage during manufacturing and use
Solution Approach 1:
The fixing element serves as a protective cushioning structure that is installed beforehand to secure the temperature sensor. This fixing element absorbs mechanical stresses and protects the fragile sensor during manufacturing processes and throughout the product's lifetime, while simultaneously maintaining stable thermal contact for accurate temperature measurement.
